Mumbai: As the world battles a chip shortage of ‘terabytic’ proportions, several Indian investors casting their net beyond the Mumbai water margin are buying into companies that make the tiny stuff that these days runs everything – from tiny hand-phones to giant SUVs.Brokerages offering foreign shares said Indian investors have traded $70-80 million in global chip manufacturing stocks the past year, with the pandemic causing a semiconductor stampede from cryptocurrency miners, mobile-phone makers and EV companies alike.This has prompted Indian investors to bet on chip manufacturing stocks. Two Nasdaq listed stocks – Advanced Micro Devices (AMD) and Nvidia Corporation – are in great demand. Both are among the largest chip manufacturers, and have nearly doubled in 2021 so far.Stockal – one of the platforms that allows Indians to buy foreign shares – says it alone saw $30 million worth of trades in both these stocks over the last one year.”AMD and NVIDIA are two of the most frequently traded stocks on Stockal and investors on Stockal would have collectively traded close to $30,000,000 worth shares of these companies,” said Sitashwa Srivastava, co-founder, Stockal. “Both these companies are well known in India – they have development centers and people are used to their products. And since their stocks have done well too, thousands of investors are buying them.”Brand recognition of these companies in India is also helping, say market participants. Both companies have a significant consumer base in India and have servicing centres in the country.Another brokerage offering foreign shares, Winvesta, says in the last three months alone its platform has witnessed a steep increase in the trading volumes of both these stocks.”The shortage of chips globally has resulted in tremendous traction in chip stocks like AMD and Nvidia. On our platform, the volumes in AMD and Nvidia stocks have grown by nearly 75% in the period of June-August,” said Prateek Jain, co-founder and president, Winvesta. “With supply disruptions not ending anytime soon, it is unlikely that the traction within these companies is likely to witness slackening anytime soon.”AMD is a California-based company with a market capitalisation of $121 billion. A single share of AMD costs $100 and the stock is currently trading at a price to earnings(P/E) ratio of 35 times, Nasdaq data showed. Nvidia on the other hand has a market cap of $511 billion with each share of the company costing $205. Nvidia stock commands a price to earnings ratio of 73 times. Nasdaq Composite, the benchmark index, is currently trading at a P/E of 28.
